After Hybrid OS to Native OS conversion in 6500, unable to wr mem
I have converted 6500 with SUP2 and MSFC2 Hybrid OS system to Native OS. After the conversion, iam not able to do wr mem. If i do wr mem, iam getting an error message of startup-config file open failed(No device available).
If the "sh startup" command is executed, i get an error like- unable to open nvram://startup-config

Probably you forgot to clear the variable CONFIG_FILE. The CONFIG_FILE environment variable is not used by the Cisco IOS (Native) software, and may cause a problem. This can easily be avoided here, by removing either bootflash:switch.cfg or slot0:switch.cfg from the environment settings.
To do this, issue the following commands:
rommon 2 > CONFIG_FILE=
!--- The CONFIG_FILE statement is case-sensitive and is all caps.
rommon 3 > sync
!--- The sync command writes the new environment variable setting to NVRAM.
rommon 4 > reset
!--- The reset command is necessary after changing any environment variable.
